The Ruth Wichelhausen papers have been arranged in five series. Series have been designated for Correspondence, Legal Documents, Personal Papers, Medical Papers, and Otto Wichelhausen's Papers. The correspondence has been further subdivided into three subseries: family, friends, and professional correspondence. The correspondence covers the period 1928-1993 and is both incoming and outgoing. The family correspondence is of special interest because most of it concerns Jewish life in Nazi Germany. Of special interest among correspondence with friends is that with Margot Nehring, dated December 1945-August 1965, which describes the lives of refugees after the Second World War. Another subject covered in the correspondence is her medical profession. Most of the correspondence with her family and friends is written in German, with some in English. Also, some of the letters on her medical profession are in German. The legal documents date from 1908 to 1994. The first subseries includes legal documents concerning the Wichelhausen family during the Nazi regime, including the claim of Ruth Wichelhausen and her brother-in-law, Felix Wichelhausen, for the property of her mother-in-law, Ida Wichelhausen. Also included are some of the last letters from her sister- and brother-in-law, Aenne and Richard Frankenberg, before they were deported into a concentration camp in 1941 and 1942. Most of these papers are written in German, but many have been translated into English. The personal papers date from 1922-1995 and include school and university papers from Germany and the United States. Also included are photographs, diaries, datebooks, brochures, newspaper clippings, obituaries, drawings, theater and opera programs, and various papers. There is also a collection of stamps and German currency. These document Wichelhausen's eclectic personal interests, ranging from gardening to her adopted hometown of Atlanta. The medical papers have been subdivided into the following subseries: hospitals & medical organizations, journals, reprints, and research. These papers date from 1913 through 1993 and offer substantial documentation of Dr. Wichelhausen's professional research and interests throughout her career. They include various publications, journals, articles, brochures, and notes on medical research. Also included are papers concerning various hospitals and medical organizations. The papers of Otto Wichelhausen cover the period 1913-1940 and include personal papers such as notebooks, correspondence, school and university papers, and various legal documents. The majority of these papers are in German.
